Subject[PATCH 3.16 091/133] MIPS: ralink: allow NULL clock for clk_get_rate
3.16.51-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jonas Gorski <jonas.gorski@gmail.com>

commit a18097b7676bf5fb2677bf5e6cc24e721d7c2596 upstream.

Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.

Fixes: 3f0a06b0368d ("MIPS: ralink: adds clkdev code")
